[0002] With the continuous expansion of the hair dye market and the increasing demand of consumers for product quality, quality control and testing in the production process of hair dyes have become particularly important. The chemical composition and concentration in hair dyes have a direct impact on their color effects, stability and safety. Therefore, accurate and rapid detection of various components in hair dyes has become a key link in the production process. As an electrochemical analysis instrument, the automatic potentiometric titrator has the characteristics of high precision, high sensitivity and high speed, which can meet the various requirements in the production and testing of hair dyes. The automatic potentiometric titrator has broad application prospects and important application value in the production and testing of hair dyes.

[0003] However, the general automatic potentiometric titrator does not have a device to fix the beaker, so that during the test, the beaker containing the reagent is easy to move, so that the inner wall of the beaker hits the burette, causing damage to the burette, resulting in low detection efficiency. For this reason, we proposed an automatic potentiometric titrator for hair dye production detection. Utility Model Content
